An effective dimensional inspection method based on zone fitting Conference Paper uri icon


  • In geometric tolerancing, minimum zone evaluation technique is used when the measured data is regarded as a copy of actual surface and the tolerance zone is represented as geometric constraints. Since functional requirements or assembly conditions on a manufactured part are normally translated into geometric constraints to which the part must confirm, it is appropriate to use zone fitting technique to evaluate part quality. This paper presents an effective dimensional inspection method based on zone fitting. With rigid body transformation, computational geometry, and nonlinear optimization techniques, the tolerances of geometric entities can be determined. The developed methodology can be applied to evaluate 2D and 3D geometry. It can be used for dimensional inspection with datum.
